This week we have Leon Wieseltier on the show, who among many other things, is the Isaiah Berlin Senior Fellow in Culture and Policy at the Brookings Institution. Wieseltier is currently completing an essay on the moral, historical and philosophical dimensions of the refugee crisis. During his conversation with Lawfare editor-in-chief Ben Wittes, Wieseltier expresses his frustrations with the United States’ policy in Syria, arguing that the United States has a moral obligation to do more to alleviate the plight of Syrian refugees and that the U.S.’s refusal to act is the great foreign policy failing of our time. According to him, the United States has a responsibility to be more than the “world’s most powerful bystander.”
